App not showing 3D map

Hi, any advice on how to show the 3D map?
There is only black screen. After completed mowing task.

Pareil, je n’ai pas de visualisation  en 3D,  juste une mauvaise  carte noire et avec un peu de vert

Hello，
The 3D map requires loading a significant amount of data. Please check if the surrounding Wi-Fi signal is strong and if the device is connected to the network. Try again in an area with a stronger Wi-Fi signal.
